There are four steps involved in setting up a drawing so that you can enter site boundaries - setting the input mode, setting the scale type, setting the angle direction and setting the angle type.

1. Click the Tools pull-down menu and set the Input Mode to Relative Polar.
2. Select Settings from the Utility menu and choose Scale Type. Pick Decimal, then right click back to the Settings menu.
3. In the Settings menu, choose Angle Type then click Compass to set North (zero degrees) toward the top of the screen.
4. Still in the Angle Type menu pick Bearings.

You may now begin entering the coordinates.

1. Start by picking the staring point for your site boundary. This point can be arbitrary as all other points will be relative to it.
2. Hit the [Spacebar].
3. DataCAD will prompt you to "Enter relative distance." Type the value in decimal feet, i.e. 48.5 for 48'-6", and hit [Enter].
4. DataCAD will prompt you to "Enter relative angle." Type the value using the format LAT Deg.Min.Sec LON, i.e. N45.15.10E, and hit [Enter].
5. DataCAD will add the line to your drawing.
6. Continue entering the coordinates using the [Spacebar] coordinate entry until you have finished the site.
